Hemarthrosis is bleeding into a joint. It often causes inflammation
Hemarthrosis is more likely to occur in people with bleeding
disorders, such as hemophilia (a rare inherited condition), or in those who use
blood-thinning medicines, such as warfarin. It also can develop after an
injury to a joint when blood vessels in the joint are also injured.
